If you are only needing it to work on the given document then I think in
general for two element nodes, the shortest relative Xpath can always be
expressed in the form


where xxx is one of a
  ancestor self preceding following descendant
and n is a positive integer

so you only have to find the two nodes decide whether one is or is not
an ancestor of the other and then use the appropriate xxx axis. Travel
along that axis until you find teh second node, then you kjnow what
number to use for n.
